Kinderchick, I have been watching the nest all morning, too. It is true that Mama Goose has been gone for over three hours, but it is a nice day here in Edmonton, sunny and about 7 above, so I am thinking that Mom knows what she is doing, and is taking a much-needed break to relax, eat as much as possible, and have a nice swim. I saw the crow and a sparrow come by and investigate, but they looked pretty nervous about sticking around, so I think there are geese in the vicinity, and possibly Mom is one of them. I have not seen anything on the Goose website to indicate that this is unusual behavior for the geese, so I am thinking she will return shortly.
